Wash the bellies very well

Place them in a bowl with a lot of vinegar and water to disinfect and whiten them, for about an hour and a half

Clean the trotters, burning or scraping any hair

Put everything in a pot with water only, just enough to cover them

Cook over low heat for about 5.5 hours or until the meat falls off the bone

Bone the legs and put them back in the pot, salt and boil for another ten minutes

Serve with garlic, vinegar and chili flakes
